Engineering plastic diaphragm pump performance summary
QBY Engineering Plastic diaphragm pump not only can exhaust the flow liquid, but also can convey some uneasy flowed medium, with the merits of self-pumping pump, diving pump, shield pump, slurry pump and impurity pump, etc.:
1. It is unnecessary to pour the drawing water, the suction lift reaches 7 m height, the delivery lift reaches 70 m length and the export pressure ≧6kgf/cm2.
2. Wide flow and good performance.The diameter allowed to pass the max grain reaches 10 mm. The damage is very less to the pump while exhausting the slurry and impurity.
3. The delivery lift and flow can pass the pneumatic valve open to realize the stepless adjustment (the pneumatic pressure adjustment is between 1-7 kgf/cm2).
4. This pump has no rotary parts and no bearing seals. The diaphragm will completely separate the exhausted medium and pump running parts, working medium. The conveyed medium can t be leaked outside. Thus it will not cause the environmental pollution and human body safety dangerous while exhausting the toxin and flammable or corrosive medium. No electricity. It is safe and reliable while using in the flammable and explire places.
5. It can be soaked in medium.
6. It is convenient to use and reliable to work. Only open or close the gas valve body while starting or stopping.Even if no medium operation or pausing suddenly for a long time because of accident matters, the pump will not be damaged caused by this. Once over-loading, the pump will automatically stop and possesses the self-protection function.When the load recovers normally, it also can start automatically.
7. Simple structure and less wearing parts. This pump is simple in structure, installation and maintenance. The medium conveyed by the pump will not touch the matched pneumatic valve and coupling lever, etc. Not like other kinds pumps, the performance will drop down gradually because of the damages of rotor, gear and vane, etc.
8. It can transmit the adhesive liquid (the viscosity is below 1000 centipoise).
9. This pump needs the oil lubricant. Even if idling, it has any influence to the pump. This is a characteristic of this pump.

Engineering plastic diaphragm pump working principle
There installs each diaphragm in both aligned working cavities (A) & (B), which can be connected together with a central coupling lever. The compression air enters the air distribution valve from the air entrance of the pump, draw the compression air into one cavity through the air distribution mechanism, push out the diaphragm movement in the cavity. The gas in another cavity will be drained. Once reaching the stroke terminal, the air distribution mechanism will automatically draw the compression air into another working cavity, push out the diaphragm to move towards the opposite direction, so as to let the both diaphragms continuously reciprocate motion in synchronism. The compression air enters the air distribution valve from (E) shown in the diagram, let the diaphragm piece move towards the right direction.And the suction force in (A) chamber lets the medium flow into from (C) entrance, push out the ball valve (2) to enter (A) chamber, the ball valve (4) will be locked due to the suction force; The medium in (B) chamber will be pressed, push out the ball valve (3) to flow out from the exit (D). Meanwhile, let the ball valve (1) close, prevent backflow. Such movement in circles will let the medium uninterruptedly suck from (C) entrance and drain from (D) exit.

Engineering Plastic diaphragm pump main usage:
1. The pump can suck the peanut, pickles, tomato slurry, red sausage, chocolate, hops, syrup, etc.
2. The pump can suck the paint, pigment, glue and adhesive, etc.
3. The pump can suck various glazed slurries of tile, porcelain, brick, chinaware, etc.
4. The pump can suck various grinding materials, corrosive agent and clean the oil dirt, etc.
5. The pump can suck various toxin and flammable or volatility liquid, etc.
6. The pump can suck various wedge water, cement slurry, mortar, etc.
7. The pump can suck various strong acid, alkali and corrosive liquid, etc.
8. It can be used as a front-step transmission device of the solid and liquid separation equipment.
